Application led November 23,1921. -Serial No. 517,231.

To all '207mm t may concern: l

Be it known that I, ROBERT HINCKLEY, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in lVave Motors; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings which form part of the specification.

My invention relates to improvements in wave motors of a simple construction that will respond quickly to every degree of wave movement and provide power for driving a shaft. y

In the drawings I have shownfrny invention as applied for driving propeller shaft? for the operation of a screw wheel of a boat. I do not, however, limit my invention to driving a screw as it is apparent that I may apply my energizing means to any shaft regardless of the ultimate power distribution of said shaft.

Referring to the drawings :-Fig. 1 is a plan view of a wave motor embodying my invention; Fig. 2 is a reduced side elevation thereof; Fig. 3 is a detail showing an end elevation, partly in cross section; Fig. 4 is a detail showing a side elevation in cross section of the transmission gearing employed.

Referring more particularly to the drawings 10 denotes a boat, barge or raft having movably attached thereto floats 11 provided with vertically disposed loop members 12, fore and Chains 13 are slidably attached thereto. The other end 4of said chains being rigidly fastened to booms or brace rods 14 which are securely fastened to boat 10 and braced by tie rods 15. In the center of the boat and running substantially parallel to the keel is journalled a shaft 16 upon which are rigidly mounted cog wheels or cog drums 17. For engagement with these drums I have provided two arms denoted by 1S and 19 said arms being swingingly connected to each other and to a link member 2O by a. bolt 21. Cogs or teeth are formed in said arms. Each arm or rack acts independently; 18 being engaged and 19 idling, on the downward stroke and upon the upward stroke the reverse is true, thus the drum is kept propelled in one direction.

It will be seen that I prefer to construct these arms or racks of curved form and to hold them together and in alternate Operati ng contact by means of a spring Link 2O 1s connected to a.y lever arm 23 yby a bolt `24.l Lever arm 23 `is fulcrumed onA the gunwale ot the boat and swingmgly necting and regulating the wave energy I have provided a spring, clutch and variable speed gearing. I have 'also shown a proeller to which this power may be transmitted for the purpose of driving my boat. It is nnderstood. however, that in case I' wish to anchor my boat, I may use the wave motor power for charging a generator vso T lorries.) i

that said power may be transmitted to the vland for operating machinery thereon or I.

may use the move motor power in any other feasible manner.

Shaft 16 is journalled in boxes 30,31 and at three points in aframe 32. A ratchetwheel 33 is pinned to shaft 16 and has an engaging pawl 34 which is pivoted to frame 32. A coil spring is fastened ,at 36 to ratchet-v wheel 33 and at 37 to spur-wheel 38fwhi`ch wheel idles upon shaft 16 and engages pinion 39 which is pinned to shaft 40 which isjournailed as shown. Upon shaft 40 is an idler gear 41 which has a hub adapted to be engaged with a. clutch means 42 for connecting and disconnectingsaid gear 41 with said and high speed gear 50. rlwo intermediate gears 51 and connected together' by a hub arc slidably keyed upon shaft 48 and operated by a gear shifting lever The above mentioned hub of gears 51 and r52 is provided with extending members to engage gears 49 and 50 respectively.

A shaft`54 carries four gears 55, 56, 57 and 58 pinned thereto and respectively adapted The movement of the outboard members is transmitted to spars pivoted to levers which are pivotally fulcrumed upon the gunwales of' said center member. rlie inboard portion of the levers connecting with substantially downwardly extendinCr racks adapted to alternately engage with cog drums which drive a center shaft. The power from this shaft is controlled by means of clutch and gearing.

l wish also to point out the advantage oit spring` This spring will take up quick shocks caused by sudden Waves or heavy swells, said spring ceiling tightly in such cases and then gradually uncoiling, thus transmits its coiled energy and regulating the speed of the propeller.

Claimsl. A wave motor having three oblong floats, booms attached to and projecting fore and aft from both sides of central float, loop members loosely connecting said side floats to said booms, levers i'ulcrumed to opposite sides of the central float their inboard and outboard ends having a vertical movement, guide rods mounted on the side floats to loosely confine the outer ends of said levers, a motor shaft mounted lengthwise in the central float and means for transmitting the vertical movement of the inboard ends of said levers to operate said shaft.

2. A wave motor having three oblong floats, booms attached to and projecting fore and att from both sides of central float, loop members loosely connecting said side floats to said booms, levers l'ulciumed to opposite sides of the central float their inboard and outboard ends having a vertical movement, guide rods mounted on the side floats to loosely confine the outer ends of said levers, a motor shaft mounted lengthwise on the central float, means for transmitting the ver* tical movement of the inboard ends of said levers to operate said shaft and a spring con trolled shock absorber for said shaft.

In testimony that I claim the foregoing as my own, I affix my signature.

ROBERT HINCKLEY.
